The reaction of 1,4-dihydro-1,4-epoxynaphthalene with cyclooctatetraene at 130 +/- 5 degrees for 14 days gave the four products 2a,3,3a,4,9,9a,10,10a-octahydro-4,9-epoxy-3,10-ethenocyclobuta[b]anthracene (13). 25-oxanonacyclo[10,10,2,2(5,9),1(14,21),0(2,11),0(3,10),0(4,6),0(13,22),0(15,20)] heptacosa-7,15,17,19,23,26-hexaene (14), 5,5a,6,6a,6b,6c,12a,12b,12c,13,13a,14-dodecahydro-5,14-epoxy-6,13-ethenocycloocta[3',4']cyclobuta[1',2',3,4]-cyclobuta[1,2-b]anthracene (15) and bis-adduct 16. The structures of the products were determined by spectroscopic methods. It was observed that adduct 14 undeergoes a Cope rerrangement. The Cope rearrangement of this adduct was investigated in the temperature range of -85 degrees to 100 degrees by NMR spectroscopy.

Rearrangement of unsaturated cyclic peroxides obtained by photooxygenation of 2,3-dimethylene-7-oxabenzonorbornene and 2,3-dimethylene-1,4-etheno-1,2,3,4-tetrahydronaphthalene Ozen, R; Kormali, F; Balcı, Metin; Atasoy, B (2001-08-27) Cobalt(II) tetraphenylporphyrin (CoTPP)-catalyzed rearrangement of peroxide 11 obtained by the photooxygenation of 5 gave a mixture of epoxides 15 (or 16) and 17. However, CoTPP-catalyzed rearrangement of peroxide 20 arising by photooxygenation of 2,3-dimethylene-1,4-etheno-1,2,3,4-tetrahydronaphthalane 6 gave 1,4-etheno-1,2,3,4-tetrahydronaphtho[b]-furan 21. The different behaviour of these endoperoxides 11 and 20 is discussed in terms of ring strain and the degree of the pyramidalization of the C=C bond
Enantioselective synthesis of (S)-2-hydroxypropanone derivatives by benzoylformate decarboxylase catalyzed C-C bond formation Dunnwald, T; Demir, Ayhan Sıtkı; Siegert, P; Pohl, M; Muller, M (2000-06-01) Chiral 2-hydroxypropanone derivatives 5a-v, 8a-d, and 10a, b were formed by benzoylformate decarboxylase (BFD) catalyzed C-C bond formation. A donor aldehyde and acetaldehyde as an acceptor were carboligated in aqueous buffer solution with remarkable ease in high chemical yield and good to high optical purity. The substrate range of this thiamin diphosphate dependent enzyme was examined to employ this benzoin condensation type reaction in stereoselective synthesis. The observed dependence of the enantiomeri...
Hydrothermal synthesis of 3D TiO2 nanostructures using nitric acid: Characterization and evolution mechanism Erdogan, Nursev; Öztürk, Abdullah; Park, Jongee (Elsevier BV, 2016-4) Various morphologies of TiO2 nanostructures were synthesized by HNO3 assisted hydrothermal treatment with respect to the acid molarity (1 M, 3 M, and 8 M), temperature (110, 140, and 180 degrees C), and time (1, 3, and 6 h). An additional sample was synthesized inside the protonated titanate nanoribbon coated vessel with the acid molarity of 8M at 140 degrees C for 3 h. The crystal structure and morphology of the nanostructures synthesized were investigated using X-Ray diffractometer, scanning electron micr...
POLYMETHYLALUMINIUM OXIDE AND STEREOREGULAR POLYMERIZATION OF PROPYLENE-OXIDE OKTEM, Z; SARI, A; ALYURUK, K (Elsevier BV, 1993-05-01) Polymethylaluminium oxide (PMAO) was prepared by reacting trimethylaluminium (AlMe3) with water in dilute dioxane solution. Several PMAO samples with different degrees of polymerizations (DP) were prepared (1 less-than-or-equal-to DP less-than-or-equal-to 7) either by changing reaction conditions or by fractionating the products. PMAO with DP about unity was found to be trimeric in dilute dioxane solutions but, in higher dielectric solvents, it partially dissociated into free ions. Electrical conductance me...
Molar volume calculated at various pressures and the Pippard relations close to the melting point in benzene Yurtseven, Hasan Hamit (2016-03-03) The molar volume of solid and liquid benzene was calculated at various pressures (at constant temperatures), and the Pippard relations were examined close to the melting point in this organic molecule.The molar volume calculated is in good agreement with the observed data, which decreases as the pressure increases up to about 150 MPa. The Pippard relations are also valid within this pressure range at constant temperatures studied here for the solid and liquid phases of benzene.
